Long Press Button Event Handler

Question

I have seen several articles such as this one describing how to handle a long press event with a button. I can follow these directions but I am wondering if it is possible to do it the same way I handled a click. The way I handled a click was to define the handler in XML as such:

<Button
    android:id="@+id/btn_NextLift"
    ...
    android:onClick="btn_NextLiftClick" />

then in code as such:

public void btn_NextLiftClick(View vw_Current) 
    {...}

I do see the boolean property longClickable in the xml but I don't see where to define an event handler so...???

TIA JB

You can't do this via XML. Instead, use:

Button button = (Button) findViewById(R.id.btn_NextLift);

button.setOnLongClickListener(new OnLongClickListener() { 
        @Override
        public boolean onLongClick(View v) {
            // TODO Auto-generated method stub
            return true;
        }
    });

Make sure this code comes after setContentView() has been called.

Also, make sure that the longClickable property is set to true.
